Uses sensors on four 50 m long wire booms to measure the electric field to study plasma convection and waves. Currents generated in each sensor reveal the density of nearby electrons. It can take up to 36 000 samples per second of the electric field and fluctuations in the plasma density. This allows it to measure the motion of plasma structures and wave fronts travelling at thousands of kilometres per second. One of the five complementary experiments which form the Wave Experiment Consortium
